Wanting to watch the latest YouTube videos from particular YouTube channels, one Lifehacker Australia reader created a free tool for making RSS feeds from YouTube usernames. Rather than just offering a straight-up feed with enclosures, though, YTPodcaster makes it easy for users of the iPod, Zune, or most any podcast-friendly player to grab MP4s from any YouTube user. So if you're, for instance, addicted to the Monty Python channel, you can have its latest clips instantly dropped on your mobile device. YTPodcaster can also quickly download video files from any YouTube URL. If you're looking for a broader feed of videos related to a search term, try Vixy's podcaster tool.
